The "official" number. Of course the deaths are over 25 and rising. RIP all the victims.

BBC News.- At least 14 people have died and another 100 were injured in Mexico City after an explosion at the headquarters of Mexico's state oil company, Pemex.

Emergency services, assisted by dogs, are searching for people trapped in the rubble. The cause of the blast is under investigation, Pemex says.

The 54-floor Pemex Executive Tower houses hundreds of employees.

Last September, 30 people died in an explosion at a Pemex gas plant in northern Mexico.

At least 13 people were killed at the scene while another person died later in hospital, Mexican Interior Minister Miguel Angel Osorio Chong told reporters.

A further 100 people were injured in the explosion. It is not clear how many individuals remain trapped beneath the rubble. Some reports have placed the figure at more than 30.

Television pictures showed debris from the blast spread out on to the street in front of the building, and Red Cross ambulances on the scene attending to the injured, our correspondent in Mexico City reports. Police have cordoned off the streets around the building, which is located in a busy commercial area of Mexico City.

Pemex said on Thursday evening it was investigating the possible causes.

The firm's chief executive, Emilio Lozoya Austin cut short a business trip to Asia and was on his way back to Mexico, the company added.
Trapped

Relatives of employees have gathered outside the building in search of information about their loved ones, local media report.

Some are said to have tried to reach employees on their mobile phones but had no reply.

"The place shook, we lost power and suddenly there was debris everywhere. Colleagues were helping us out of the building," eyewitness Cristian Obele said.

"We were talking and all of sudden we heard an explosion with white smoke and glass falling from the windows," another witness said.

"People started running from the building covered in dust. A lot of pieces were flying."

Images of the blast posted on Twitter revealed large clouds of smoke billowing from the building. TV footage showed people being transported from the scene by helicopters. President Enrique Pena Nieto and Mexico City Mayor Miguel Angel Mancera headed to the scene of the blast. Mr Nieto said Pemex rescue and security teams were working alongside city authorities to help the injured.

"I am deeply sorry for the deaths of our fellow workers at Pemex. My condolences to their relatives," Mr Nieto said on Twitter.

"At the moment, the priority is to help the injured and protect the physical safety of those who work there."

The president said he has ordered an investigation into the causes of the blast. Earlier on Thursday, Pemex had reported problems with the electricity in the building in a message on Twitter. It later confirmed that an explosion had taken place "in the B2 building of the administrative center".

"There are injuries and damage on the ground floor and mezzanine," it said.

Plaster had fallen from the ceiling of the basement and the situation was "delicate", a spokesman for local emergency services was quoted by the Reuters news agency as saying.

Pemex has experienced a number of fatal accidents in recent years.

Last September's deadly blast at a gas plant near the northern town of Reynosa is thought to have been caused by a build-up of gas.

"A government official, speaking on condition of anonymity, said a preliminary line of inquiry suggested a gas boiler had blown up in the building to the side of the main tower that houses administrative offices. "

A gas boiler that blow up 2 whole basement levels just like the 1993 WTC bombing... yeah right! There is something rubbish here that its even restricted to the highest ranked officials. My feeling is that was intentional.

It was a hit from los narcos and a warning to the newly appointed Mexican President of what is to come if he doesn't succumb to them.

Interesting theory but the problem is that if was attack was assisted by people that how all about bombings like a terrorist organization. Funny thing is that some Cartels have contacts with terrorist factions, but well... who knows?

Like I said this situation its just too rubbish, because there are too many loose ends and not enough evidence.

Yeah, but then again the news only reports what it wants you to know. Money talks, and let's admit it. Most, if not all, of the MAIN cartels have more money than the government itself so therefore have them and their officials in the palm of their hands. Who knows though, we will probably never know.

Of course the goverment "reduce" the deaths... and the number will rise and rise but no one except the authorities and PEMEX will know.

Two whole basement levels filled with hundred of people at 1-2 PM reduced to a massive rumble of course the deaths will be over 100, there alot of bodies trapped down there. The damage looks similiar like the 1993 WTC bombing.

Yeah, I noticed the death toll wasn't that high but the injuries were. In the forthcoming days that will change though. Totally unexpected and a tragedy to have this happen. Hopefully everything is sorted out in a timely manner, but in the meanwhile prayers to those involved.

Tragedies happends, RIP all the official and unofficial victims. How bad was the tragedy that even the President goes to the "zone zero" a couple of hours after the explosion.
